It weighs 2,400 tons, has a diameter of five meters, a vertical height of 70 meters, and a height of about 20 floors. It is the world's largest hydrogenation reactor... This is the "Zhenhai ebullated bed residual oil forging welding hydrogenation reactor" developed by China First Heavy Industry Group. .

How powerful is this machine?

This is the world's largest residual oil hydrogenation equipment, and it is also the world's largest petrochemical equipment and largest reaction vessel so far.

Due to changes in the current global fuel use structure and increasing demand for light fuels, one of the key research directions in the chemical industry is how to improve the conversion rate of crude oil into light fuel oil.

The current effective method is the residual oil hydrogenation process, which uses high temperature, high pressure and catalysts to crack macromolecules into small molecules, thereby producing qualified light fuels. This reaction has high and high requirements for pressure vessels, so the importance of this equipment in China First Heavy Industry is self-evident in the chemical industry in my country. As an effective means of deep processing of heavy oil at present, the ebullated bed hydrogenation method is more flexible in operation, and can convert difficult-to-use heavy oil and residual oil into gasoline and diesel oil with higher economic value, and has a very broad prospect in the world.

In order to install this 2,400-ton behemoth, China has also continuously set a number of world records for lifting petrochemical equipment. Due to the insufficient hoisting capacity of the terminal cranes, two 850-ton cranes and a 1,600-ton crane were used to transfer it ashore. The floating crane set a new record for cargo hoisting in the Yangtze River waterway, and its installation in place shows that China has also taken the lead in the world in the technical field of large-scale petrochemical equipment installation.

It is precisely because of this that our country has the most advanced oil processing technology at present. Even the United States has no technology that can surpass China in this field, and this equipment has also been included in the list of prohibited exports by the country. Never for sale.

Of course, it is by no means an easy task to manufacture this device. In this regard, Yizhong Group has put in a lot of hard work for several years to make it successfully come out. The fluidized bed residual oil hydrogenation technology has high adaptability to raw materials, flexible operation, can reduce the coking load, and is outstanding in terms of utilization rate and environmental protection effect. In the manufacturing process, because the structure of the ebullated bed reactor is different from that of the traditional fixed bed reactor, the internal parts installation process is complicated, the processing precision is high, and the manufacturing is extremely difficult. The majority of process technology and front-line employees have strict project management, strict process specifications, and strict quality supervision. With superb manufacturing technology and solid work style, they have successively overcome many problems such as overlength and overweight reactors, heat treatment, flaw detection, and welding difficulties. High-quality Manufacturing tasks were completed efficiently. Its successful manufacturing has not only enhanced the specialization ability, innovation ability and core competitiveness of China Yizhong, but also refreshed the research and development performance of my country's super large tonnage forging welding hydrogenation reactor, which has written a new chapter for Yizhong to realize the localization of major petrochemical technology and equipment. new chapter.
